The plugin for discovering and managing EAP 5.1 instances is the jboss-as-5 plugin, which is indeed part of the EAP plugin pack. If you don't see the EAP plugin pack on the CSP it might be because your subscription doesn't entitle you to it. I would look for it one more time and if you still don't see it anywhere on the CSP, contact your sales rep and ask them for help.
Thanks for the reply Ian.
Well I am using an evaluation version of the Jboss EAP so not sure about the whereabouts about the plugin packs.
Is there a place from where I can download the same?
Any help would be highly appreciated
Either here if it's part of a JBoss subscription that you have:
or here if it's part of your evaluation:
However, I just logged on myself and I don't see any plugin packs listed on the eval download page, so you will probably need to contact your sales rep to request access to the EAP plugin pack.
